For steelhead I usually use size 2, 1 and 1/0 hooks and I fish those with sand shrimp tails via a drift rig. (Save the heads for when u run out of tails or want a change up)

I use an egg loop setup on my leader and will take the hook and run it from the front/top of the tail and exit above the hard tail fins of the shrimp. Then secure with the egg loop so it stays in place.

Under a bobber I usually set it up the same way and don’t use the heads. If really murky I’d maybe throw a whole one on.

However, from a boat using a backtroll you can use a whole shrimp but with a double hook rig so you can secure it properly.
